Improvement in packing for oil-well tubes



UNITED STATES PATENT OEEICEo CHARLES L. NOE, OF BERGEN POINT, NEV JERSEY.

IMPROVEMENT IN PACKING FOR OIL-WELL TUBES.

Specification forming part of Letters Patent No. 49,544, dated August 22, 1865.

fo all whom it may concern:

Be it known that I, CHARLES L. NOE, of Bergen Point, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in the Construction of Seed-Bags or Devices for Packing the Oil-Tubes in the Bores of Oil-Wells, and I do hereby declare that the following' is a full, clear, and exact description of the same, reference being had to the, drawings which accompany and forni a part of this specification.

Of these drawings, Figure 1. is a view of the seed-bag with the exterior covering removed, showing the means employed to operate it. Fig. 2 is a central vertical section of the seedbag. Fig. 3 is a view of the upper face ofthe bottom Iiange. Fig. 4 is a view of the upper face ot' the top iiange, these two last-named figures showing the holes and pins through and over which the cords or ropes pass, and those pins to which they are attached for the purpose of operating the seed-bag.

Similar letters of reference in the several drawings indicate corresponding parts.

The nature of my said invention consists in providing oil-wells with a packing which can be quickly and easily operated, shifted, and removed, and which, from the arrangement of its parts, will be more effective and wear longer than any packing yet constructed.

To enable others to make and use my invention, I will proceed to describe it in detail.

a is a flange forming the bottom ofthe bag, and b a iiange forming the top, both formed with a round opening in the center to admit of their passage up and down the well and around the oil-pipe when in use. On the surface of the flanges a b, I affix, by means of cordage or other suitable i'astenings, an inner cylinder of leather or its equivalent, which surrounds the round opening in the said flanges. On the rim or periphery d d of the iianges a b, I affix another cylinder of leather or its equivalent, thereby making a receptacle between these two cylinders, in which is to be inserted the seed or other suitable stuffing material. I then pass one end of astout cord or rope, c c, through one of the small holesffin the upper flange of the seed-bag, down and around one of the two pins g g, which are placed opposite each other upon the upper face of the lower iiange, then up and over one of the two pins g g, placed opposite each other upon the under face of the upper flange and equidistant from the holes ff, and then fasten it down to one of the two pins 7L h; and the other end of the cord or rope I pass through the other of the small holesj'f, and arrange itin a similar manner with respect to the remaining pins upon the flanges a b. It is clear that friction-rollers, small pulleys, or other suitable devices could be substituted for these pins. I place in the upper face ot' the flange b two screw-eyes, i i, arranged opposite each other and equidistant from the holes through which the cord or rope e e passes. Into these eyes I attach cords or ropesjj, being for the purpose of raising, lowering, or shifting the apparatus at pleasure.

Having filled the receptacle between the two leather cylinders with a suitable stuffing material, (and I prefer to insert axseed or tallow, for reasons hereinafter stated,) and the cord or rope e e being already adj usted through the holes in the upper ange and around the respective pins of the anges, as above stated, the apparatus can be easily lowered into the well by gravity, and when the point is reached at which it is necessary to have the seed-bag pack the well a short pull on the cord or rope e e will instantaneously effect the packing by drawing the respective ends of the cord or rope e e shorter around the pins on the flanges a b, and thereby cause the iiaxseed or tallow to swell or press in a side direction all around and against the two inner sides of the iexible cylinders,"andI thereby render a close and perfeet packing between the oil-pipes and the side of the well, when a slacking of the cord or rope e c and a strain upon the cords or ropesjj will cause the packing to quickly release itself' and enable the operator to shift it to any desired distance up and down the well or withdraw it altogether.

I prefer the iiaxseed as a packing, and also prefer to construct the cylinders of leather, for the reason that the water percolatin g slightly through the cylinders will cause the ilaxseed to swell, and thereby give a constantly-enlargL ing watertight packing. rIallow also is an ex-L cellent substance for stuffing. Leather is also preferable for the cylinders, on account of its tween them, operating and for the purpose better adaptation to irregularities in the Well, substantially es herein described. combined with its greet durability. 2. The application and arrangement of the What I claim as myzinvention, and desire to cord or ropejj and eyes z' i with the seed-bag, secure by Letters Patent, isas herein described.
